About Alzheimer, schizophrenia: Schizophrenia and Alzheimer’s are both diseases of the brain that can cause dramatic symptoms. They are different in many ways, but there are some similarities between both.

Both can be related with psychotic symptoms.

They can include Hallucinations (visions) or Delusions (misunderstandings).

Hallucinations are false sensual observations, which can involve someone believing they are seeing things, hearing things, touching things, or smelling things, but these perceptions are not real.

Delusions are false beliefs, such as someone believing that they are being followed, believing they are not human or believing they have a incurable illness, though there is nothing to support the accuracy of the beliefs.

About creating of ‘Super - smart mice’:

Scientists of UK Dr. Steve Clapcote and Dr. Alexander McGirr have created intelligent and bold mice by changing a single DNA by a belief that it will provide new treatments for brain disorders such as Alzheimer’s, schizophrenia and post - traumatic stress disorder.

This study was led by researchers at the University of Leeds in UK and Mount Sinai Hospital in Toronto.

Researchers altered a DNA to prevent the activity of an enzyme called phosphodiesterase - 4B (PDE4B), which is present in many organs of the vertebrate body, including the brain.
